Here is a guide to crab species identification of 4 of the most common crabs- C. Clypeatus, C. Compressus, C. Perlatus, and C. Rugosus. C. Clypeatus- Purple Pincher, PPColor- Most commonly tan or brown, but can be orange, purple, or close to blackBig Pincher- Most commonly purple. Lacks the distinct “stitch mark” of other species. Smooth to the touch.Rightmost leg- Most commonly red. Smoother than other legs.Legs- long, even, thin, and covered in dominantly visible black setae, bumps or dots where hair grows after moltEyes- small and rounded, usually dark brown, black, or redBody- long and sleek, thin and roundedTemperament, misc- known to swap shells more than any other species. Most common crab sold at pet stores.Typical PP Crabbie by therealmemeki, on FlickrPP Shawnash by therealmemeki, on FlickrLarge PP Alpha by therealmemeki, on FlickrC. Compressus- Ecuadorian, EColor- tan, grey, brown, orange, blue, yellow, always multicoloredBig Pincher- seems smaller and more “crude” than other species. Coarse bumps. Entire “arm” of pincher seems fatter than that of other species. Has stitch mark.Rightmost leg- very long, almost sickle shaped, smooth, only leg without leg tip colorLegs- thin and covered with stripes. Tips are different color than rest of legEyes- “compressed,” tall and thin, eye stalks shaped like candy corn. Eye color commonly black but red also seen.Body- large and flat. Distinct stripes on side of head.Temperament, misc- Hyperactive. Moves very quickly. Feels very light when lifted. Due to flat body, prefers shells with D-shaped openings.E Flash, and more painted shell garbage by therealmemeki, on FlickrE exoskeleton pieces Not for the squeemish by therealmemeki, on FlickrMicro E’s Micro crabs by therealmemeki, on FlickrE fresh after a molt Eddie by therealmemeki, on FlickrC. Perlatus- Strawberry crabs, strawsColor- all one color, most commonly red, can be dark red or white depending on health, once case of a brown straw recorded, white bumpsBig pincher- Covered in white bumps, very slight stitch mark, shape comparable to that of ERightmost leg- smoother than others, large and fatLegs- covered in white bumps, seem crude and pointy, thick, fat, all same colorEyes- shape similar to that of E, color of hematite (gunmetal grey) or olive greenBody- very large, covered in white bumpsTemperament, misc- Almost always sold in large size. Very fragile species requiring very intricate care. In most areas, they are no longer sold in stores.Strawberry crab Hematite eyes by therealmemeki, on FlickrYoung straw Geno by therealmemeki, on FlickrStraw BP in shell C. Perlatus pincher by therealmemeki, on FlickrC. Rugosus- RuggiesColor- green, grey, pink, purple, blackBig pincher- top hinge very small, texture like fine sandpaper, very dominant stitch mark. BP usually with stripe down middle.Rightmost leg- completely unique texture, almost like peach fuzz, looks smooth and chalky regardless of colorLegs- short, thin, almost completely flat, covered in hairs that resemble peach fuzz, tips different color than rest of legEyes- lima bean shaped, set far apart from one another, very commonly blackBody- very short and fat, small, has markings on head similar to head stripe of E’s but not as dominantTemperament, misc- Everything about the Ruggie is dwarflike. Very small and short in every way. Commonly mistaken with E’s but the difference in stature is clear when compared side by side. Swift and “skittish” movements. Appears to no longer be sold in stores.Ruggie BP in shell C. rugosus pincher by therealmemeki, on FlickrAnother example C.
